Abstract: 1. A system for electrically transmitting information with a high level of security, in particular a radio relay system, wherein a plurality of transmission channels are provided, and monitoring- and switch-over devices which, in the event of disturbances in a transmission channel, initiate a stand-by connection, characterised by a stand-by transmitter (hot stand-by) (Sh ) which is in the operating state, is connected to a control device (StE) and which can be connected via a routing line (RL), without the interposition of a channel separating filter, to the input of a transmitting channel separating filter which includes the routing lines for the connection of the individual transmission channels, further characterised by short-circuiting or interrupting elements (X) which are arranged in the individual transmission channels, can be controlled by the control device (StE) and which disconnect the disturbed transmitter (S) when the stand-by transmitter is connected and additionally prevent the absorption of the same-frequency hot stand-by signal in this channel separating filter (KF), and further characterised by the connection and disconnection, without the use of a channel separating filter, of a hot stand-by receiver (Eh ) which is arranged at the receiving end.

Title: Arrangement for measuring engine torques
IPC: G01L5/26
Filed: 1982-12-17
Abstract: An arrangement is proposed for measuring engine torques, in particular for road vehicles using internal-combustion engines. The arrangement consists of a flow (flow-rate) meter (2) for the respective fuel consumption, a tachometer (revolutions counter) (3) for the engine speed, an electronic characteristic memory (10) for the engine torque, which contains a characteristic map containing lines of equal fuel consumption plotted against engine speed, and a position measuring device (8) for the position of the accelerator pedal (7). In order to determine the torque, a search is made for the characteristic of the measured fuel consumption which is associated with the measured speed, and the associated engine torque is output thereafter. If two engine torques at different levels are possible for a given speed, the correct value is determined with the aid of the position of the accelerator pedal. <IMAGE>

Title: Pressurised gas machine, especially a compressor, with circulating lubrication
Inventor: STREICHER MAX
IPC: F04C29/02
Filed: 1983-06-18
Abstract: The machine housing (1) of a vane cell compressor is subdivided by a partition wall (2) into a lubricant chamber (4) and a working chamber (3) in which the rotor (5) is mounted tightly on the oil sump (8) in an eccentric fashion with respect to its centre and so that it can rotate about a horizontal axis (6). Hydraulic oil passes from said pump through the transverse duct (13) into the ascending duct (16) up to above the lubricant level (15). Above this, a connection piece (27) is fixed to the partition wall in the gas chamber (17). From its reversing chamber (28) a syphon pipe (29) is led down far below the lubricant level (15) and a nozzle pipe (31) is led to the lubricating nozzle (9) directed in the partition wall (2) into the machine chamber (3). The reversing chamber (28) is also connected to the working chamber (3) by way of a duct (33), which may also have a ball non-return valve (32), and a further relief duct (not shown), which may also be provided with a throttle, connects the gas chamber (17) to the function chamber (7) of the working chamber (3). This ensures that the lubricant is kept circulating under the working pressure of the machine but cannot drain into the working chamber during interruptions in operation. <IMAGE>
Patent DE-3326324-A1 (DE)
Title: Method and device for soil rehabilitation in the root area of plants, especially trees
Inventor: SCHLEITZER ROLF-PETER
IPC: A01G29/00
Filed: 1983-07-21
Abstract: The invention relates to a method and a device for soil rehabilitation in the root area of plants, especially trees, a first probe introducing a blast of compressed air into the soil, so that the soil lifts and breaks open. Cracks are formed in the soil, into which cracks a filling material is introduced which, together with the compressed air, is passed through the probe into the soil. After the ventilation of the soil and filling of the cracks, the first probe is removed from the soil and a second probe is introduced into the same hole. Through the second probe, water and, if required, fertiliser is introduced into the soil. The second probe has lateral apertures in the region of its lower end through which the water enters the soil, and the water then being distributed in the cracks. Between the lateral apertures and the upper end of the second probe, arranged on the peripheral surface of the probe, is a sleeve which has a thread on its outside which can be driven into the soil by rotation. The method and the device permit ventilation of the soil followed by deep irrigation of the soil, as a result of which the soil can be fed with moisture and, if required, fertiliser even when the surface of the soil has already been compacted again.

Title: Articulation kinematics of a control and safety device for a closeable flap arranged in an aperture
Inventor: VETTER HARALD DIPL ING
IPC: E05F15/71
Filed: 1983-09-19
Abstract: The invention relates to articulation kinematics of a control and safety device for a closeable flap arranged in an aperture, especially for a domelight, pitched-roof window, greenhouse window, etc., where the actuating member is filled with an expansion medium, according to P 2138947. The control device according to the invention differs from the known devices in that scissor constructions generating highly unstable lifting conditions are not used, but instead the flaps are actuated by direct engagement via a well-defined centre of rotation, a suitable lifting transmission nevertheless being ensured.

Patent DE-3337742-A1 (DE)
Title: Silencer for an internal combustion engine
Inventor: WAGNER WALTER
IPC: F01N1/08
Filed: 1983-10-18
Abstract: A silencer for an internal combustion engine comprises an outer envelope tube (1), inside which at least one gas-guiding tube (4, 10) is arranged, the gas-guiding tube (4, 13) being provided at the circumference, in each case in the region of cuts extending parallel to the longitudinal axis of the gas-guiding tube, with protrusions which, together with the surface of the gas-guiding tube, define flow openings (26), the plane of which is essentially perpendicular to the surface of the gas-guiding tube and at least parallel to the longitudinal axis of the latter. These flow openings thus allow gas to flow out in the peripheral direction. The slope of the projecting surface relative to the inner surface of the gas-guiding tube is such that the flow does not separate from this surface, swirling and pressure losses due to the latter thus being prevented by these protrusions. The aim of the gas-guiding tube according to the invention is, by diverting some of the exhaust gases and the soundwaves through these flow openings, to achieve silencing characterised by minimum pressure losses inside the gas-guiding tube.   <IMAGE>

Title: Apparatus and process for separating foreign substances from a gas stream
Inventor: HUETTLIN HERBERT
IPC: B01D47/06
Filed: 1984-02-28
Abstract: A wall which can be crossed by a gas stream is provided with deflectors (14) which form inlet channels (16) narrowing in the incoming flow direction and which end in a smoothing bulge (18). A concave baffle (20) is arranged behind each deflector, which baffle forms a dome, at a distance, around the smoothing bulge (18).
